@hangc0276 @Technoboy- @poorbarcode Please help to review it.

Since the PR #21188 will cherry-pick into branch-3.0, branch-2.11 and branch-2.10 and the test is very flaky, I added the labels release/2.10.6, release/2.11.3 and release/3.0.2

[lhotari]

Great work @horizonzy!

[lhotari]

This will help reduce flakiness a lot. Please cherry-pick also to branch-3.1 since that will be maintained for some time.

Sure.
